What are the key symptoms of inhaling CO2 from a fire extinguisher?

Inhaling CO2 from a fire extinguisher can lead to specific symptoms primarily affecting the respiratory and neurological systems. Dizziness arises as the body responds to reduced oxygen levels. A headache may develop due to lack of oxygen or changes in carbon dioxide levels in the blood. Difficulty breathing occurs as the respiratory system struggles to process the increased CO2 and potentially reduced oxygen availability. These symptoms serve as critical indicators that immediate action is needed to return to an area with adequate ventilation and fresh air.

The other response options encompass symptoms that are not typically associated specifically with CO2 inhalation. While some symptoms might overlap with other conditions or exposures, they do not accurately represent the focused effects of CO2 inhalation.
